ject of this invention 1s to construct a s delight or scuttle ofthischaracter of very few partsso as-toattain simplicity of design and economy in production, and, moreover, to devise those parts so that the operation is easy but very'reliable in effect. a

These improvements are equally applicable to' circular' andoval or elliptical side-lights and are advantageously adapted so that the closureorsash mOYes inwardly against its seating, whereby external pressure of wave, or wind tends to increase'the-water-tightness of the closed condition.

Accordingto thisinvention, the trunnions or diametral pivotsjof the closure or sash, which are movable in guides perpendicular to the plane of the seating, are adjusted in;

those guides by engagement with cams .or revoluble means on the framing-in order' to adjustthe closure or sashirom or towards its seating. These cam devices 'or -revoluble means alone may produce the strong pressing" of a sash against its seating in the closed con-' dition, butthe possibility using auxiliary te th p p s isnq ex,e ude .To ena e th ven i a b r a-di y derstQQd, reference is made to the accomf panying drawi gsi mt na y W y xample, oneconstruction embodying the pres ent improvements, in which drawings Figure 1 is an elevation as seen from the iu ers deofa por rop nin iE-igure 2 :is a ce tral vert ca section of Figure 1.

In=the example illustrated in the drawing,

the framing ais cylindrical with a .flangeb at one end for fixin g to a support which may beItheskin 'oi a ship. At the other or inner end,the cylindrical frame is formed or fitted with an inner grooved ring. or rim 0, the

groove having inserted into it a. suitable seat-L ing ring, such as. rubber ring (5. At diamet ricallyoppositepoints, as at the topand hot r,

tom of the vertical diameteiythe cylindrical frame is formed with slots 6 parallel with its: central axis. Atthe said points, the framing a'is formed with flats orlbosses fextending on either. side of each slot, and a cover or box 9 is'iastened, -asiby screws,against eachyof these flats. Eachcoverorbox g is recessedto receive a disc cream :72) the recess being elongated so that its sides 9" Figures 2 and 6, serve asaguideior the disc or canih. More over, each cover or boxlg isiormed "with a slot 9? to serve as a guide for a-stubj on which said disc or cam h 'is fixed or formed. -The slot 9 in each cover or'box'g extendsatright angies to the adjacent slot-e in the'frame a, as seenin Figure 3. TheLsash ringia for the circularilight-xl is fitted at diametrically opposite points Iwith pivot pins or trunnions m 'm/which are slidablyengaged in the slots esof the cylindrical frame aTWhen thesash kisinserted into the frame a... 'Each pivot pin extends through. its appropriate slot 6 in the framing and such extension isengaged in aperforationlof its respective cam or.;disc

h.disposedlexternally of the slotted part of, the framing. "The stubs-:j of thediscs or cams h extend through the guide slots g in the box or cover 9 to a sufiicient extent for the engagement therewith of the hubs n of an operating handle 0 and for the reception of fixingnuts p. The operating handle 0 is advantageously a semi-circular bail, asseen in Figure 1, formed with a radiusgreater than that of the circular light and having at the, ends the hubs n'adapted for engagement with the stubs j as aforesaid. Let it be assumed" that the circular sash la is hard against its seatingd in the frame a and that in this condition the operating handle 0 lies in a plane parallel with that of the sash k,-as illustrated in Figures 1 to 3. The trunnions or pivots m m are then at the inner ends of the slots 6 in the frame and, as regards their engagement with the discs or cams it, may be regarded as crank pins on, or about on, a dead centre. When it is desiredto open the sash,

the operating handle 0 is swung through an angle of 180. Thiscauses the discs or cams h to revolve through a like angle but as such discs or cams are engaged with the pivot pins or trunnions which can only move rectilinearly, along the slots 6 in the cylindrical frame, the said discs or cams it move along the guides g in the boxes or covers 9 at right angles to, the slots e in the frame,

, th eirstubs moving along the slots g in the boxes orcovers g. The reaction between the discs h and the pivot pins or trunnions m m causesithe latter to move outwardly-in the slots 0 of the cylindrical frame a so that the sash la is moved bodily away from its seating d to such a distance as will enable the sash 7a to be swivelled about the pivot pins or trunnions m m'wto an open position. If it is dey sired to secure the sash 7c in a partly open position, as when it has been swivelled to an angle of less than 90 to the plane of its seating d, the operating handle 0 can be reversely operated through a small angle so, as to cause the sash or glass holder 70 to wedge itself, as it were, against points in the circular aperture To enable the parts to be readily assembled,

v the trunnion m may be a stud which is inserted through the sash ring is from the interior thereof and screwed into such ring, the

projecting shank portion serving as pivot as seen clearly in Figures 2 and 6." The other trunnion m may be a stud screwed into the sash ring is from the exterior, see Figure 2,

and so that the head of such stud remainspros jecting to serve as the trunnion or pivot pin. Byremoving the appropriate box or cover g,

fitis possible to get at the stud m and after removal of such stud, and removal or disengagement of the disc h associated with the other stud m,'the sash is removable from the framing a withthe said other stud m intact.

Provision can be made for fitting to the sidelight a portable watertight deadlight g, Figures 4 and 5,by forming alip or bead r on the inner surface of the fixed frame a and two wedge lugs s on its outer diameter. The deadlight g has a spigot t to locate its position in the fixed frame, two projecting wedgesu on its outer diameter to: engage with the wedge lugs of the fixedtframe, and a rubber jointing ring 1; for engagement with the bead r. r c

On .sidelig hts of exceptional size, when it may be considered unsuitable'that the application of pressure should be applied to two pivot pins; only for forcing the "glass.

holderhinto the rubberseating ring, addi-- tional pressure may be appliedthrough two swing fastenings, as illustrated invFigu'res 7 and 8. e For example, at two diametrically opposite points onthe .sash ring 70: lugs may be formedand adapted for engagement by p votedhooks or catches a2.

of the screws 2 brings their inneren'dshard against the rim 0 of the frame a, so that fur{ ther screwing forces the links g away from the rim cwhereby ,the hooks m are caused to pull the sash is strongly against itsseating d;-

As stated above these swing fastenings may be considered desirable in some cases, .butas the rubber seating ring (Z is on' the inboard side of thesash or glass holder is, any pres-o sure from water striking the glass Z only tends to increase water-tightness, so thatgadditional pressure means,such as the devices shown in Figures 7 and 8, may generally be dispensed with. p 3 p v t Inside lights in accordancewith these improvements, it is possible to reglaze a glass holder is whilst the latter in the main frame m V I I From Figuresl to 3 and 6,1it will be seen that the hubs n of the handle 0 are of larger diameter than the discs it and that each of such hubs a is fitted near its periphery with a metallic joint ring n for hearing against the outer surface of a respective box or cover The inner diameter of this joint ringn" is such that the slots 9 lie within the ring n at all times and throughout the range of operation'of the handle 0 from the closed it the full op'en'position. Thus,'the joint ringsfl will always prevent water 'or other'matter from entering the ship through the slots Iclaimf' 1.
